AI Technical Summary

Technical Problem

Conventional reinforcing members for supporting eaves in building roofs are limited in placement due to their design, restricting the arrangement of inclined members and reducing the design freedom of the roof support structure, which can compromise the strength and construction efficiency.

Method used

A reinforcing member with a base portion, shaft portion, and arm portion that allows for insertion through a vertical hole in a structural shaft member, enabling easy attachment to the upper surface of columns or horizontal members, and utilizing holes aligned with existing metal pin holes for secure fixation, allowing for flexible placement and connection with other structural elements.

Benefits of technology

Enhances the design freedom and constructability of roof support structures by allowing easier attachment to columns without interfering with other components, improving the strength and efficiency of roof corner support.

Abstract

A reinforcing member (60) reinforces inclined members (53) for supporting eaves. The reinforcing member (60) comprises: a base part (61) that is disposed on the upper surface of a framework shaft member (20X); a shaft part (62) that extends downward from the lower surface of the base part (61) and is inserted into a vertical hole (23C) of the framework shaft member (20X); and an arm part (63) that is disposed on the framework shaft member (20X) and supports the inclined members (53). The arm part (63) has an arm plate (64) brought into contact with side surfaces of the inclined members (53). The arm plate (64) extends obliquely downward from the upper surface of the base part (61) such that in a plan view, a leading end portion (64A) of the arm plate (64) is positioned outward of the base part (61) and in a side view, the leading end portion (64A) of the arm plate (64) is positioned downward of the base part (61). The arm plate (64) is provided with first holes (63A) into which first coupling members (65) for coupling the inclined members (53) and the arm plate (64) are inserted.
